Factories and Science Facilities on the top of the inaccessible hills

Factories and Science Facilities should not be on the top of the inaccessible hills, where I can't pick up it - it doesn't make sence, right? (And the number of Factories and Science Facilities in each game is limited, so - if some of them are not awaylable - it is sad...)Also, mineral shard pickups and gas pods have to be accessible even on the top of hills: I could land my snockpile or other building to pick it up (now it says something aboud wrong landing zone - it shoud be changed)
